💡 Note: Ensure that you have the necessary permissions and dependencies installed before proceeding with the installation.

# Download the Bosun binary
wget https://github.com/bosun-monitor/bosun/releases/download/v0.8.0/bosun-linux-amd64

# Make the binary executable
chmod +x bosun-linux-amd64

# Move the binary to a directory in your PATH
sudo mv bosun-linux-amd64 /usr/local/bin/bosun

Configuration

Once installed, Bosun needs to be configured to collect metrics and generate alerts. The configuration is done through a YAML file, where you can specify data sources, alerting rules, and other settings. Here is an example of a basic Bosun configuration file:

# Bosun configuration file
collectors:
  - name: "example-collector"
    type: "http"
    url: "http://example.com/metrics"

alerts:
  - name: "cpu-usage-alert"
    condition: "cpu_usage > 80"
    actions:
      - type: "email"
        recipients: ["admin@example.com"]

Integration with Data Sources

Bosun can integrate with various data sources, including Prometheus, Graphite, and custom HTTP endpoints. To integrate Bosun with a data source, you need to configure the appropriate collector in the configuration file. Here is an example of integrating Bosun with Prometheus:

# Bosun configuration file
collectors:
  - name: "prometheus-collector"
    type: "prometheus"
    url: "http://prometheus.example.com"
